Aglaonema plant named ‘TWYAG0013’

ABSTRACT

A new  Aglaonema  plant particularly distinguished by a small stature, dense leafy, compact, full and mounded growth habit, green leaves with pink blotches, profuse suckering, consistent progressive growth and produces numerous axillary branches and leaves, is disclosed.

Genus and species: Aglaonema rotundum×A. costatum hybrid.

Variety denomination: ‘TWYAG0013’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct cultivar of Aglaonema, botanically known as Aglaonema rotundum×A. costatum hybrid, and hereinafter referred to by the cultivar name ‘TWYAG0013’. The new cultivar originated from a hybridization made in 2000 in Bogor, Indonesia. The female parent was an unknown individual plant of A. rotundum (patent status unknown), while the male parent was an unknown individual plant of A. costatum (patent status unknown). A single plant was chosen for further selection in February 2002.

The new cultivar was created in Bogor, Indonesia and has been asexually reproduced repeatedly by vegetative cuttings, and sucker division in Apopka, Fla. and Bogor, Indonesia over a 5-year period. The present invention has been found to retain its distinctive characteristics through successive asexual propagations.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishing characteristics of this new cultivar when grown under normal horticultural practices in Apopka, Fla. and Bogor, Indonesia.

-   -   1. Small in stature;     -   2. Densely leafy, compact, full and mounded growth habit;     -   3. Green leaves with pink blotches;     -   4. Profuse suckering;     -   5. Consistent progressive growth; and     -   6. Produces numerous axillary branches and leaves.

DESCRIPTION OF THE PHOTOGRAPH

This new Aglaonema plant is illustrated by the accompanying photograph which shows overall plant habit. The colors shown are as true as can be reasonably obtained by conventional photographic procedures.

DESCRIPTION OF THE NEW CULTIVAR

The following detailed description sets forth the distinctive characteristics of ‘TWYAG0013’. The data which defines these characteristics were collected from asexual reproductions carried out in Apopka, Fla. The plant history was taken on 6-month old plants started from a single 4-leaf rooted cutting, still in a vegetative state and grown in Apopka, Fla. Rooted cuttings were planted in 15-cm pots and grown in a greenhouse in August 2006. The average daily temperature was about 85° to 95° F. and the average nightly temperature was about 72° to 78° F. Color readings were taken under natural light. Color references are primarily to the RHS Colour Chart of The Royal Horticultural Society of London (RHS) (2001).
